DRAW-BAR GARRY-IRON.

Specification of Letters Patent.

Patented July 2'2, 1915.

To all whom it may concern:

Be it known that we, EUGENE H. CROWN, a citizen of the UnitedStates, residing at Sacramento, California, and CHARLES T. WnsTLAKn and CHARLES S. Sl-IALLENBERGER, citizens of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Draw Bar Carry-Irons, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains' to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in Which-= Figure 1 is a top plan view of a striking plate with which a carry iron of our improved construction is combined. Fig. 2 is a front elevational view of the carry iron in position on a striking plate. Fig. 3 is a verticalsectional view taken approximately on the line 3+3 of Fig. 2. Fig. 4 is a vertical section taken approximately on the line 4-4 of Fig. 2. Figs. 5 and 6 are perspective views of bearings which are located in the striking plate and which support the hangers forming a part of our improved carry iron. Fig. 7 is a perspective view of one of the hangers. Fig. 8 is a top plan view of one end of the carry iron.

Our invention relates to new'and useful improvements in supports or hangers for the drawbars of railway cars, the principal object of "the invention being to provide a comparatively simple hanger whichfu nder all conditions will readily accommodate itself to the backward and forward movement of the drawbar resulting from draft and huifing strains, and the lateral swing or movement. of the drawbar resulting from the passage of cars around curves in the to move freely in both directions and in tically equal in both directions, that is, longitudinally and transversely, the carry iron which supports said bar should be permitted order to prevent the drawbar from sliding upon the surface of the carryjiron, the latter should be supported in such a manner as to perinit the drawbar to move longitudinally and transversely at the same time. To accomplish this result, we propose tomount the carry iron upon hangerswhich are supported from a fixed part ofthe car body, n'cferably the striking plate, universal joints, which arrangement permits said carry iron to move freely in alldirections under the influence of'the supported drawhar.

As the movement of the drawbar in each direction is approximately three inches from its normal central position, the rise of said drawbar when swinging would be considerableif the hangers were short, but in our improved contruction, hangers are provided which are of such lengththat the drawbar will be free to move the necessary distance in any direction without contacting with the under surface of the striking plate.

A further object of our invention is to provide a drawbar hanger or support which can be readily assembled or taken apart, and which when in position for use, cannot become accidentally displaced by reason of undue vibration or jolting of the car or drawbar.

' With the above and other objects in view,

our invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed.

Referring by numerals to the accompanying drawings, 10 designates the 'base of a striking plate which is applied to a. car end' sill or buffer beam in any suitable manner and formed integral with said base and projecting forwardly therefrom is ahorizontally disposed plate 11 provided on its front and ends witha vertically disposed wall or flange 12. The central portion of this striking plate is reinforced by integral webs or walls 13, which arearrang'ed between the front wall 12 and the plate 10, and formed in the plate 11 between these walls and the walls 12 on the ends of said plate are openings 14 for the accommodation of the upper ends of the carry iron hangers. Formed in one of the walls 13 is an aperture 15 and formed on the plate 11 on the opposite side of .the adjacent opening 14 is a bearing seat 16. This seat and the aperture 15 serve as bearings for the trunnions 22 of a pivot block 23, which latter is provided in its upper side with a seat 24 for one of the carry iron hangers. Forrned-in the other of the walls 13 is an inclined notch 20 and formed on the plate 11 on the opposite side of the corresponding opening 14 is a bearing seat 21. This notch and seat serve as bearings for the trunnions 17 of a pivot block 18, which latter is provided in its upper side with a bearing 18 for the upper end of one of the carry iron hangers.

One of the hangers forming a part of our invention is shown in Fig. 7 the same comprising a shank 25, with the upper end of which is formed integral, a loop 26, the up- .per end thereof being formed into a trans verse journal 27. The lower end of the shank 25 is provided with a pair of oppositely arranged and horizontally disposed journals 28.

The carry iron as contemplated by our invention is formed in a single piece, preferably by casting, and comprises a pair of heads 29 and an intermediate body portion 30, the same being provided with a pair of oppositely disposed bearing faces 31 which are preferably convex in cross section. One of these convex bearing faces is located nearer to the longitudinal axis of the carry iron than the other, and thus, by reversing the position of said carry iron or turning it upside down, the height at which the supported drawbar is carried can be varied.

Formed through the heads 29 are vertically disposed inwardly extending slots h 32 and formed in the upper and lower surfaces of said heads to the sides of these slots are seats or bearings 33 which are adapted to receive the journals 28. A bolt or like fastening device 34 is seated in the wall 13 immediately to the rear of the inclined notch 20 and in the adjacent end wall 12 and immediately over the upper end of the corresponding hanger, thereby providing means for preventing the accidental displacement of the device while the same is in use.

In assembling our improved drawbar sup port the bearing blocks 18 and 23 are inserted through the loops at the upper ends of the hangers with thejournals 27 on said hangers occupying the'bearings 19 and 24, after which said bearing blocks are positioned immediately over the. openings 14 with the trunnions on the ends of said blocks occupying the bearings 1 and 16 and 20 and 21. The carry iron comprising the heads 29 and body 30 is now positioned between the hangers with the journals 28 pcsitioned in the lower pairs of bearings 83.

As the supported drawbar shown by dotted lines in Figs. 2 and 3 moves longitudinally of the car under bufiinguor pulling strains, the carry iron will swing backward and forward with said drawbar during which movement the trunnions on the ends of the bearing blocks 18 and 23 rock in their respective seats.

During the transverse swinging movement of the supported drawbar which takes place during the passage of the car around a curve in the track, the carry iron on the lower ends of the hangers 25 swings transversely of the car during which movement the journals 27 and 28 rock in their respective bearings.

By our improved arrangement of mounting the carrier on the striking plate, the hangers for the carry iron are provided at their upper ends with substantially universal joints, and for this reason the supported drawbar can move longitudinally and transversely at the same time without appreciable wear or strain upon any of the parts of the support.

The entire carrier is comparatively simple, can be easily and cheaply manufactured, and is capable of being readily assembled or taken apart.

lVc do not desire to be limited to the exact arrangement and details of construction herein shown and described, as it will be readily understood that the principle and characteristic features of the invention may be embodied in other devices difiering specifically in detail more or less from those herein shown and described.

We claim:

1. In a draw bar carrier the combination with a support provided with openings and aving pairs of bearings formed at the sides of said openings, which bearings are transversely disposed with respect to the supported draw bar, of a pair of pivot blocks provided with trunnions which occupy said bearings, hangers supported from said pivot blocks, and a carry iron supported by said hangers.

2. In a drawbar carrier, the combination with a support, of a pair of hangers, pivot blocks forming a connection between said hangers and the support, which pivot blocks are provided with trunnions which are seated in bearings in the support and with bearings which receive the upper ends of the hangers, whereby said hangers are permitted to swing longitudinally and transversely with respect to the car to which the hanger is applied, and a drawbar carry iron sup ported by said hangers.

3. In a drawbar carrier, the combination with a support, of a pair of pivot blocks mounted for roclnng movement thereon, which blocks are transversely disposed with respect to the supported draw bar, hangers, the upper ends of which are provided with loops which engage in transversely disposed earings formed in the pivot blocks, and a drawbar carry iron supported by said hangers.

4. In a drawbar carrier, the combination with a pair of hangers provided with trunnions on their lower ends, of a carry iron, the ends of which are slotted to accommo date the hangers, and there being bearings formed in the upperand lower faces of said carry iron adjacent to the slots therein to receive the trunnions on said hangers.

5. The combination with a support provided with openings and bearings formed to the suspended from said pivotblocks, .a carry iron pivotally supported-by seidhangers, and seated in the support eboyeone of the pivot blocks for preventing the with- 20 drawal of the adjacent pivotbloelgsirom its bearings.
